Having tested the JBL 2414H-C, I’m eager to see the outcome of the K-700 with my Pyle PDB512, a titanium midrange compressi9on driver. The PDB512 is a bolt driver. On her own, she cannot be attached to the K-700 because her throat is screw. Luckily, I have a Bolt to Screw mount adapter and I managed to mount the PDB512 to the K-700. Klipsch K-700 with Pyle PDB512 Fig 1 is the RAW response of the K-700 with the Pyle PDB512 mounted. No crossover is used and the plot is not smoothed. As I had hoped, the response reached down to 700Hz. This is the frequency where the K-700 was used in the Heresy 1. She is more or less flat from 1kHz to 3kHz, after which she tapers to 6kHz at about 10dB/oct. At 8kHz, there is a cone breakup.
The Impedance is in Fig 2. The main peak is just after 1kHz. This is very close to 700Hz which is the frequency I intend to use. I will definitely need to use a conjugate network to flatten this peak otherwise she’ll scream when the music hits this resonant frequency. As for the peak at 200Hz, she’s quite far away. There’s no need for treatment. Summary Now that I’ve measured the Pyle PDB512 with the K-700, I’m confident this combo is workable. My next step is to see how well this combo sounds like when combined with the 10″ B&C 10CL51 Neo woofer. If it works, it will emulate the response of the Heresy 1. Unless otherwise stated, all measurements were made in Full Space (4 pi) with the mic at 36 ins, tweeter axis. Impulse Window=5ms. No smoothing applied. |
